gr-qc/0611112 [abs, ps, pdf, other] :: Title: Effective constraints of loop quantum gravity
Authors: Martin Bojowald, Hector Hernandez, Mikhail Kagan, Aureliano Skirzewski
Comments: 44 pages, 6 figures

Within a perturbative cosmological regime of loop quantum gravity corrections to effective constraints are computed. This takes into account all inhomogeneous degrees of freedom relevant for scalar metric modes around flat space and results in explicit expressions for modified coefficients and of higher order terms. It also illustrates the role of different scales determining the relative magnitude of corrections. Our results demonstrate that loop quantum gravity has the correct classical limit, at least in its sector of cosmological perturbations around flat space, in the sense of perturbative effective theory.

Authors: Sante Carloni, Peter K. S. Dunsby, Claudio Rubano
Comments: 19 pages, 3 figures, accepted for publication on PRD

The covariant gauge invariant perturbation theory of scalar cosmological perturbations is developed for a general Scalar-Tensor Friedmann-Lemaitre-Robertson-Walker cosmology in a vacuum. The perturbation equations are then solved exactly in the long wavelength limit for a specific coupling, potential and background. Differences with the minimally coupled case are briefly discussed.
hep-ph/0608070 [abs, ps, pdf, other] :: Title: Neutrino Flavor States and the Quantum Theory of Neutrino Oscillations
Authors: Carlo Giunti
Comments: 20 pages; final version, to be published as a Topical Review in Journal of Physics G: Nuclear and Particle Physics

The definition and derivation of flavor neutrino states in the framework of standard Quantum Field Theory is reviewed, clarifying some subtle points. It is shown that a flavor neutrino state that describes a neutrino produced or detected in a charged-current weak interaction process depends on the process under consideration and is appropriate for the description of neutrino oscillations as well as for the calculation of neutrino production or detection rates. Hence, we have a consistent framework for the description of neutrino oscillations and interactions in neutrino oscillation experiments. The standard flavor neutrino states are obtained as approximations which describe neutrinos in experiments that are not sensitive to the dependence of neutrino interactions on the neutrino mass differences. It is also shown that the oscillation probability can be derived either through the usual light-ray time = distance approximation or through an average of the space-time dependent oscillation probability over the unobserved propagation time.
hep-th/0611205 [abs, ps, pdf, other] :: Title: Gyromagnetic Ratio of Charged Kerr-Anti-de Sitter Black Holes
Authors: A. N. Aliev
Comments: 4 pages, Latex

We calculate the gyromagnetic ratio of rotating anti-de Sitter black holes carrying a single angular momentum and a test Maxwell charge in all higher dimensions. We show that the value of the gyromagnetic ratio crucially depends on the dimensionless ratio of the rotation parameter to the curvature radius of the anti-de Sitter background. In the critical limit, when the boundary Einstein universe is rotating at the speed of light, the gyromagnetic ratio approaches the value g=2 regardless of the spacetime dimensions.
hep-th/0611224 [abs, ps, pdf, other] :: Title: Aspects of a supersymmetric Brans-Dicke theory
Authors: Riccardo Catena
Comments: 5 pages

We consider a locally supersymmetric theory where the Planck mass is replaced by a dynamical superfield. This model can be thought of as the Minimal Supersymmetric extension of the Brans-Dicke theory (MSBD). The motivation that underlies this analysis is the research of possible connections between Dark Energy models based on Brans-Dicke-like theories and supersymmetric Dark Matter scenarios. We find that the phenomenology associated with the MSBD model is very different compared to the one of the original Brans-Dicke theory: the new scalar and fermionic degrees of freedom do not couple to matter in a universal metric way, i.e. they can not be removed from the matter sector by a Weyl rescaling of the metric. This feature could make the minimal supersymmetric extension of the BD idea phenomenologically inconsistent.

Comments: 10 pages, no figs, LaTeX
Journal-ref: Phys. Lett. B 641 (2006) 381

The black-body radiation is considered in a theory with noncommutative electromagnetic fields; that is noncommutativity is introduced in field space, rather than in real space. A direct implication of the result on Cosmic Microwave Background map is argued.

gr-qc/0611120 [abs, ps, pdf, other] :: Title: First attempt to dynamically constrain the quadrupole mass moment of millisecond pulsars
Authors: Lorenzo Iorio
Comments: LaTex2e, 11 pages, no figures, 4 tables, 25 references

In this paper we attempt to dynamically constrain the quadrupole mass moment Q of the millisecond PSR B1257+12 pulsar from the orbital periods of its three planets, assumed to be in equatorial and circular orbits. Given the present-day accuracy in knowing their ephemerides, no post-Newtonian corrections to their motions are required. By conservatively assuming 1% and 10% uncertainties in the pulsar's mass and planets' semimajor axes, respectively, our determination of the adimensional parameter q=c^4 Q/G^2 M^3 is q=(-0.90 +/- 67.45) 10^12, so that Q=(-1.08 +/- 80.22) 10^49 kg m^2. As an independent check of such a result, we apply the same method to the binary system composed by the millisecond PSR J1909-3744 pulsar and a white dwarf in circular orbit. We find for such a pulsar q=(-0.76 +/- 21.18) 10^12 and Q=(-0.98 +/- 27.26) 10^49 kg m^2, which are consistent with the estimates for PSR B1257+12.

In this letter we dynamically determine the quadrupole mass moment Q of the magnetic white dwarf WD 0137-349 by analyzing the period of the recently discovered brown dwarf moving around it in a close 2-hr orbit. It turns out that a purely Newtonian model for the orbit of WD 0137-349B, assumed circular and equatorial, is adequate, given the present-day accuracy in knowing the orbital parameters of such a binary system. Our result is Q=(-1.4615 +/- 0.9004) 10^47 kg m^2. It is the first dynamical, model-independent measurement of the quadrupole mass moment of a white dwarf.

We study the indirect detection of neutralino dark matter using positrons and gamma rays from its annihilation in the galactic halo. Considering the HESS data as the spectrum constituting the gamma--ray background, we compare the prospects for the experiments GLAST and PAMELA in a general supergravity framework with non--universal scalar and gaugino masses. We show that with a boost factor of about 10, PAMELA will be competitive with GLAST for typical NFW cuspy profiles.

Authors: Pei-Hong Gu, Hong-Jian He
Comments: 5 pages. Typos corrected and references added. Accepted for publication in JCAP

We extend the visible content of the standard model (SM) with a hidden sector composed of three right-handed singlet neutrinos and one singlet Higgs. These extra singlets are charged under a new U(1)_X gauge symmetry while the SM particles are not. Two heavy scalar doublets are introduced to play the role of the messengers between the visible and hidden sectors. The neutrinos naturally acquire tiny Dirac masses because the ratio of weak scale over the heavy messenger masses is highly suppressed. Furthermore, the heavy messengers simultaneously generate baryon asymmetry of the universe through their out-of-equilibrium CP-violating decays.
hep-th/0611259 [abs, ps, pdf, other] :: Title: Colliding Branes in Heterotic M-theory
Authors: Jean-Luc Lehners, Paul McFadden, Neil Turok
Comments: 28 pages, 4 figures

We study the collision of two flat, parallel end-of-the-world branes in heterotic M-theory. By insisting that there is no divergence in the Riemann curvature as the collision approaches, we are able to single out a unique solution possessing the local geometry of (2d compactified Milne)/Z_2 x R_3, times a finite-volume Calabi-Yau manifold in the vicinity of the collision. At a finite time before and after the collision, a second type of singularity appears momentarily on the negative-tension brane, representing its bouncing off a zero of the bulk warp factor. We find this singularity to be remarkably mild and easily regularised. The various different cosmological solutions to heterotic M-theory previously found by other authors are shown to merely represent different portions of a unique flat cosmological solution to heterotic M-theory.

In cores of supernovae and crusts of neutron stars, nuclei can adopt interesting shapes, such as rods or slabs, etc., which are referred to as nuclear "pasta." In recent years, we have studied the pasta phases focusing on their dynamical aspects with a quantum molecular dynamic (QMD) approach. In this article, we review these works. We also focus on the treatment of the Coulomb interaction.

gr-qc/0611132 [abs, ps, pdf, other] :: Title: The interior spacetimes of stars in Palatini f(R) gravity
Authors: Kimmo Kainulainen, Vappu Reijonen, Daniel Sunhede
Comments: 5 pages, 1 figure

We study the interior spacetimes of stars in the Palatini formalism of f(R) gravity and derive a generalized Tolman-Oppenheimer-Volkoff and mass equation for a static, spherically symmetric star. We show that matching the interior solution with the exterior Schwarzschild-De Sitter solution in general gives a relation between the gravitational mass and the density profile of a star, which is different from the one in General Relativity. These modifications become neglible in models for which $\delta f(R) \equiv (R)-R$ is a decreasing function of R however. As a result, both Solar System constraints and stellar dynamics are perfectly consistent with $f(R) = R - \mu^4/R$.
gr-qc/0611137 [abs, ps, pdf, other] :: Title: Radiation and Potential Barriers of a 5D Black String Solution
Authors: Molin Liu, Hongya Liu, Lixin Xu, Paul S. Wesson
Comments: 9 pages, 3 figures, accepted for publication on MPLA

By using a massless scalar field we examine the effect of an extra dimension on black hole radiation. Because the equations are coupled, we find that the structure of the fifth dimension (as for membrane and induced-matter theory) affects the nature of the radiation observed in four-dimensional spacetime. In the case of the Schwarzschild-de Sitter solution embedded in a Randall-Sundrum brane model, the extension of the black hole along the fifth dimension looks like a black string. Then it is shown that, on the brane, the potential barrier surrounding the black hole has a quantized as well as a continuous spectrum. In principle, Hawking radiation may thus provide a probe for higher dimensions.
hep-th/0611157 [abs, ps, pdf, other] :: Title: Self-accelerating Warped Braneworlds
Authors: Marcela Carena, Joseph Lykken, Minjoon Park, Jose Santiago
Comments: 21 pages, 6 figures

Braneworld models with induced gravity have the potential to replace dark energy as the explanation for the current accelerating expansion of the Universe. The original model of Dvali, Gabadadze and Porrati (DGP) demonstrated the existence of a ``self--accelerating'' branch of background solutions, but suffered from the presence of ghosts. We present a new large class of braneworld models which generalize the DGP model. Our models have negative curvature in the bulk, allow a second brane, and have general brane tensions and localized curvature terms. We exhibit three different kinds of ghosts, associated to the graviton zero mode, the radion, and the longitudinal components of massive graviton modes. The latter two species occur in the DGP model, for negative and positive brane tension respectively. In our models, we find that the two kinds of DGP ghosts are tightly correlated with each other, but are not always linked to the feature of self--acceleration. Our models are a promising laboratory for understanding the origins and physical meaning of braneworld ghosts, and perhaps for eliminating them altogether.

Authors: N. Khosravi, H. R. Sepangi, M. M. Sheikh-Jabbari
Comments: 13 pages, 4 .eps figures

We consider a class of generalized FRW type metrics in the context of higher dimensional Einstein gravity in which the extra dimensions are allowed to have different scale factors. It is shown that noncommutativity between the momenta conjugate to the internal space scale factors controls the power-law behavior of the scale factors in the extra dimensions, taming it to an oscillatory behavior. Hence noncommutativity among the internal momenta of the mini-super-\emph{phase}-space can be used to explain stabilization of the compactification volume of the internal space in a higher dimensional gravity theory.

hep-ex/0611050 [abs, pdf] :: Title: Q & A Experiment to Search for Vacuum Dichroism, Pseudoscalar-Photon Interaction and Millicharged Fermions
Authors: Sheng-Jui Chen, Hsien-Hao Mei, Wei-Tou Ni
Comments: 21 pages, 13 figures, submitted to Modern Physics Letters

A number of experiments are underway to detect vacuum birefringence and dichroism -- PVLAS, Q & A, and BMV. Recently, PVLAS experiment has observed optical rotation in vacuum by a magnetic field (vacuum dichroism). Theoretical interpretations of this result include a possible pseudoscalar-photon interaction and the existence of millicharged fermions. Here, we report the progress and first results of Q & A (QED [quantum electrodynamics] and Axion) experiment proposed and started in 1994. A 3.5-m high-finesse (around 30,000) Fabry-Perot prototype detector extendable to 7-m has been built and tested. We use X-pendulums and automatic control schemes developed by the gravitational-wave detection community for mirror suspension and cavity control. To polarize the vacuum, we use a 2.3-T dipole permanent magnet, with 27-mm-diameter clear borehole and 0.6-m field length,. In the experiment, the magnet is rotated at 5-10 rev/s to generate time-dependent polarization signal with twice the rotation frequency. Our ellipsometer/polarization-rotation-detection-system is formed by a pair of Glan-Taylor type polarizing prisms with extinction ratio lower than 10-8 together with a polarization modulating Faraday Cell with/without a quarter wave plate. We made an independent calibration of our apparatus by performing a measurement of gaseous Cotton-Mouton effect of nitrogen. We present our first experimental results and give a brief discussion of our experimental limit on pseudo-scalar-photon interaction and millicharged fermions.

Authors: R. Holman (Carnegie Mellon University), L. Mersini-Houghton (UNC-Chapel Hill), Tomo Takahashi (Saga University)
Comments: 7 pages, 1 figure

We investigate the effects of quantum entanglement between our horizon patch and others due to the tracing out of long wavelength modes in the wavefunction of the Universe as defined on a particular model of the landscape. In this, the first of two papers devoted to this topic, we find that the SUSY breaking scale is bounded both above {\em and} below: $10^{-10} M_{\rm P}\leq M_{\rm SUSY}\leq 10^{-8} M_{\rm P}$ for $GUT$ scale inflation. The lower bound is at least five orders of magnitude larger than the expected value of this parameter and can be tested by LHC physics.

Authors: Cristiano Germani (DAMTP, KCL & SISSA), N.E. Grandi (IFLP-Conicet, ICTP & SISSA), Alex Kehagias (Natl. Tech. U., Athens)
Comments: v2: figures improved

We propose a cosmological model, alternative to the standard inflationary paradigm, where all problems that afflict standard non-inflationary cosmology are naturally solved. In this model, the Universe is a wandering brane moving, with non-zero angular momentum, in a warped throat on a Calabi-Yau space. It is assumed that mirage effects drive the cosmic evolution at early time. The result is a bouncing cosmology without cosmic singularity as experienced by an observer living on the brane. Density perturbations are calculated in our model and we find a slightly red spectral index, in compatibility with WMAP data.

Authors: Marcello Musso (University of Texas at Austin)
Comments: 13 pages, includes a modified version of axodraw.sty that works with the Revtex4 class

In this paper we provide an alternative method to compute correlation functions in the in-in formalism. We develop a modified set of Feynman rules that allows for an easier computation of loop corrections. With respect to the standard in-in formalism (where the diagrammatic representation is very compact but the evaluation of each diagram is rather involved and contains many different contributions), in our formulation the major effort is devoted to drawing the diagrams, while their mathematical interpretation is straightforward. Our method is particularly suitable for applications to cosmology.
hep-th/0611293 [abs, ps, pdf, other] :: Title: End of multi-field inflation and the perturbation spectrum
Authors: Jinn-Ouk Gong
Comments: (v1) 16 pages, 5 figures, 3 tables; (v2) 17 pages, references added, typos corrected

We investigate the dynamics of inflation models driven by multiple, decoupled scalar fields and calculate the Hubble parameter and the amplitude of the lightest field at the end of inflation which may be responsible for interesting, or possibly dangerous cosmological consequences after inflation. The results are very simple and similar to those of the single field inflation, mainly depend on the underlying spectrum of the masses. The mass distribution is heavily constrained by the power spectrum of density perturbations P and the spectral index n. The overall mass scale gives the amplitude of P and n is affected by the number of fields and the spacing between masses in the distribution. The drop-out effect of the massive fields makes the perturbation spectrum typically redder than the single field inflation spectrum. We illustrate this using two different mass distributions.

Authors: Charles A. Nelson, Paresh R. Shimpi
Comments: 16 pages; version 3 to improve wording
Subj-class: Mathematical Physics

This paper shows that in intensity correlation measurements there will be clear and unambiguous signals that new-physics particles are, or aren't, parabosons. For a parabosonic field in a dominant single-mode, there is a diagonal P-representation in the "even and odd coherent states" basis. It is used to analyze zero-time-interval intensity correlations of parabosons in a maximum-entropic state. As the mean number of parabosons decreases, there is a monotonic reduction to (2/p) of the constant bosonic ``factor of two'' proportionality of the second-order versus the squared first-order intensity correlation function.

hep-ph/0611359 [abs, ps, pdf, other] :: Title: Gamma Ray Burst Neutrinos Probing Quantum Gravity
Authors: M.C. Gonzalez-Garcia, F. Halzen
Comments: 14 pages, 2 figures

Very high energy, short wavelength, neutrinos may interact with the space-time foam predicted by theories of quantum gravity. They would propagate like light through a crystal lattice and be delayed, with the delay depending on the energy. This will appear to the observer as a violation of Lorenz invariance. Back of the envelope calculations imply that observations of neutrinos produced by gamma ray bursts may reach Planck-scale sensitivity. We revisit the problem considering two essential complications: the imprecise timing of the neutrinos associated with their poorly understood production mechanism in the source and the indirect nature of their energy measurement made by high energy neutrino telescopes.

Comments: 3.3 pages, no figures

A.M. Hillas, in a review of the origins of cosmic rays, has recently criticized the "cannonball" (CB) model of cosmic rays and gamma-ray bursts. We respond to this critique and take the occasion to discuss the crucial question of particle acceleration in the CB model and in the generally accepted models. We also summarize our claims concerning the CB model.
hep-ph/0611378 [abs, ps, pdf, other] :: Title: Dark energy and the hierarchy problem
Authors: Pisin Chen
Comments: Submitted to the DM06 Proceedings (to be published by Nuclear Physics B)

The well-known hierarchy between the Planck scale (~10^{19}GeV) and the TeV scale, namely a ratio of ~10^{16} between the two, is coincidentally repeated in a inverted order between the TeV scale and the dark energy scale at \~10^{-3}eV implied by the observations. We argue that this is not a numerical coincidence. The same brane-world setups to address the first hierarchy problem may also in principle address this second hierarchy issue. Specifically, we consider supersymmetry in the bulk and its breaking on the brane and resort to the Casimir energy induced by the bulk graviton-gravitino mass-shift on the brane as the dark energy. For the ADD model we found that our notion is sensible only if the number of extra dimension n=2. We extend our study to the Randall-Sundrum model. Invoking the chirality-flip on the boundaries for SUSY-breaking, the zero-mode gravitino contribution to the Casimir energy does give rise to the double hierarchy. Unfortunately since the higher Kaluza-Klein modes acquire relative mass-shifts at the TeV level, the zero-mode contribution to Casimir energy is overshadowed.
nucl-ex/0611040 [abs, ps, pdf, other] :: Title: Recent Results from RHIC & Some Lessons for Cosmic-Ray Physicists
Authors: Spencer R. Klein
Comments: 8 pgs; invited talk presented at the XIVth International Symposium on Very High Energy Cosmic Ray Interactions (ISVHECRI 2006)

The Relativistic Heavy Ion Collider (RHIC) studies nuclear matter under a variety of conditions. Cold nuclear matter is probed with deuteron-gold collisions, while hot nuclear matter(possibly a quark-gluon plasma (QGP)) is created in heavy-ion collisions. The distribution of spin in polarized nucleons is measured with polarized proton collisions, and photoproduction is studied using the photons that accompany heavy nuclei.
The deuteron-gold data shows less forward particle production than would be expected from a superposition of $pp$ collisions, as expected due to saturation/shadowing. Particle production in $AA$ collisions is well described by a model of an expanding fireball in thermal equilibrium. Strong hydrodynamic flow and jet quenching shows that the the produced matter interacts very strongly. These phenomena are consistent with new non-perturbative interactions near the transition temperature to the QGP.
This writeup will discuss these results, and their implications for cosmic-ray physicists.

We report on the calibration of a superfluid $^3$He bolometer developed for the search of non-baryonic Dark Matter. Precise thermometry is achieved by the direct measurement of thermal excitations using Vibrating Wire Resonators (VWRs). The heating pulses for calibration were produced by the direct quantum process of quasiparticle generation by other VWRs present. The bolometric calibration factor is analyzed as a function of temperature and excitation level of the sensing VWR. The calibration is compared to bolometric measurements of the nuclear neutron capture reaction and heat depositions by cosmic muons and low energy electrons. The comparison allows a quantitative estimation of the ultra-violet scintillation rate of irradiated helium, demonstrating the possibility of efficient electron recoil event rejection.
